Shilajit is traditionally used in Ayurveda to boost energy, testosterone, and stamina, which can help improve sexual performance. However, clinical evidence specifically validating 'Shilajit Mega Power Capsules' is limited, and individual results vary. The price generally ranges from 500 rupees to 1,500 rupees (15 dollars to 30 dollars), depending on the retailer and package size. Since sexual stamina concerns can stem from underlying medical conditions, stress, or lifestyle factors, I highly recommend consulting a doctor before starting this supplement to ensure it is safe and appropriate for your health.
